The oil cooler seals are leaking my rebuilt 2.0l. Any advice how tight to bolt the cooler down to ensure a good seal? Haynes manual helpfully states 'not too tight, and not too little' I'm thinking a smidge of Hylomar would help?
Tighten all 3 nuts , give it half hour, go back ,see if you can get them to tighten a bit more. , use a ring spanner ,not a big ratchet. Use the right seals. I would tighten them down the same as the inlet manifold nuts.
..as far as i remember they suposed to b torqued to 5 or 6 ft lbs.. Wysłane z iPad za pomocą Tapatalk
Stripped the engine down to replace the seals, there's three washers which go on the bolts, which in theory should restrict the compression of the seals anyway?
I did wonder @3901mick, but the manual says 'Do not forget the washers between the cooler and the crankcase' ?
99.9% they all go on outside mate, Mine did and no leaks, stripped several for parts and never had them between the cooler and housing. Only on type 1
There is a section on the Samba where it goes through the different cooler designs. Some require thick washers between the face of the cooler and the block, some have built in standoffs.. Coolers are installed correctly if there is a bit of a gap between the cooler and the engine block and wrong if there is no gap - the seal gets too squashed and restricts cooling oil flow. I think modern coolers have the standoffs so no washer underneath..
Brilliant, I'll get onto this tonight (rain stopped play last night) Thanks for all your helpful replies!
Well, yep that cleared up the problem! I'm guessing lazy editing from an earlier manual by the Haynes team is to blame...
